The opposed faces of the meeting rails of the sashes 19 are provided with interlocking tongues and grooves as shown at 27 so a's to provideA a substantially water tight connec tion between said rails when the sashes are closed. However, I also provide these faces ofthe sash rails with longitudinally extending grooves 28 which constitute air receiving pockets to evaporate moisture and keep the sash rails dry. However, any water which may find its way into the groove in the rail of the upper sash will be drained off by the outwardly and downwardly inclined grooves or channels 29 at the ends of the grooves 28 and directed to the outer sides of the sash.

In conjunction with the shoe member 20 and for the purpose of locking the window frame at the top and sides thereof to the wall structure, I provide at the inner side of the frame the bars 30 each having a longitudinally extending rib 31 locking in a groove 31 in the frame. The upper side of thisbar opposed' to the frame is cut away or recessed at 32 in opposed relation to the recess or channel 33 in the face of the@ window frame,

' said mating recesses receiving the cement indicated at 34 whereby the bar 29 and the window frame are united to the wall structure. It wil-l be noted' that the recess o r channel 33 extends around the corner of the .brick Work or masonry within which the window frame is set so that the cement will ythus produce a very secure lock. By this means, the possibility of the window lframe pulling away from the wall at the top there# of is obviated. l

From the foregoing description considered in connection with the accompanying drawgc, itis believed that the construction and several novel features of lmy lpresent im; proveniente will be. clearly understood. By

'the provision'on the spaced bearing ribs for the' sliding sashes, limiting the `area of contact, friction is reduced to a minimum, and in addition, air spaces are provided between said ribs which serve as collecting and drainage'channels for moisture and alsofhave a 20 beneath the window frame and the addi-v 'tional course of brick 23, shifting or displacement of the frame due to warpage from the effects of the sun, will be prevented. Thus, I have produced a windowconstruction which is very substantial, comparatively inexpensive and in which the sash'es may be raised or lowered with a minimum of eort while at the saine time preventing/the inward seepage4 of water between the sashes and the frame and also preventing a substantially air tight closure when the sashes are in closed\position.

While I have herein shown and described a simple and practical embodiment of my invention, it will nevertheless be understood that thefseveral features herein disclosed are susceptible of more or less modification, and I therefore, reserve the privilege of adopting all such alternative construct-ions as lmay be fairly incorporated within the spirit and scope of the invention as claimed.

I claim:

1. In a. window construction, a frame, parting strips secured to the opposite sides of theframe, vertically sliding sashes 1nounted in the frame at each side of the parting strips, each side of the frame on opposite'` v'sides of the parting strip being provided with spaced vertically extending beads of semi-circular orm in cross section with Which the respective sashes have sliding bearing contact.

2. In a window construction, a frame,

parting strips secured to the opposite sides y of the frame, vertically sliding'l sashes -mounted in the frame at each side of the parting strips, each side ofthe frame on opposite sides of the parting strip being provided with spaced vertically extending beads of -semi-circular form in lcross section with which the respective sashes have sliding bearing contact, and fsailvd?. frame and the parting strips being provided with similar vertical beads having bearing contact with the inner and outer faces respectively of the vertical sash Stiles.

In testimony that I claim the foregoing as my invention, I have signed my name hereto.

ALBERT ENTENMAN.
